\section{Main results}
Here is an example of a definition.
\begin{definition} Let $A$ be a $C^*$-algebra. A mapping
$\phi :A\rightarrow \mathbb{C} $ is
called a positive linear functional on $A$ if it satisfies the following conditions:
\begin{enumerate}
\item $\phi(\alpha x+\beta y)=\alpha \phi(x)+\beta\phi(y)$ for all $\lambda ,\beta \in \mathbb{C}$ and $x,y\in A$.
\item $\phi(x)\geq 0$ for all $a\geq 0$ in $A$.
\end{enumerate}
\end{definition}

Here is an example of a table.
\begin{table}[ht]
\caption{}\label{eqtable}
\renewcommand\arraystretch{1.5}
\noindent\[
\begin{array}{|c|c|c|}
\hline
1&2&3\\
\hline f(x)&g(x)&h(x)\\
\hline a&b&c\\
\hline
\end{array}
\]
\end{table}
Here is an example of a matrix.
\begin{equation*}
\begin{bmatrix}
1 & 2 \\
3 & 4
\end{bmatrix}
\end{equation*}
Here is an example.
%---------------------------------------------------------------------------------------%
\begin{example} Let $A$ be the $C^*$-algebra of $n\times n$ complex matrices. Define $Tr: A\rightarrow \mathbb{C}$ to be the canonical trace of a matrix. Then we have
\begin{equation}\label{2.1}
Tr(\alpha x+\beta y)=\alpha Tr(x)+\beta Tr(y).
\end{equation}
for all $\lambda ,\beta \in \mathbb{C}$ and $x,y\in A$. It follows that $Tr$ is linear functional on $A$.
\end{example}
%---------------------------------------------------------------------------------------%
The following is an example of a theorem and a proof. Please note how to refer to a formula.
%---------------------------------------------------------------------------------------%
\begin{theorem}\label{theo1}
Let $G$ be a finite group acting on a second countable compact Hausdorff space $X$. Suppose that $\mu$ is a finite Borel measure on $X$. Then the induced bimodule $\mathcal{H}_\mu\times \mathcal{H}_\mu$ has almost central unit vectors.
\end{theorem}
%---------------------------------------------------------------------------------------%
\begin{proof}
Since $f$ is uniformly continuous on $X$ there exists $\delta>0$ such that $|f(x)-f(y)|<\epsilon$ for all $x,y\in X$ with $d(x,y)<\delta$. It follows that
\begin{align}\label{eq}
|f(xr)-f(yr)|&=|f(xr)-f(yr)|\nonumber\\
&=|f(xr)-f(yr)|\nonumber\\
&< \epsilon
\end{align}
for all $x,y\in E_n$, $r\in G$, $n>\frac{2}{\delta}$. Let $\bigtriangleup = \{(s, s): s\in G\}$ be the diagonal of $G\times G$. It follows from Equation~\eqref{eq} that $||\pi(f)U(r)\zeta_n-\zeta_n\pi(f)U(r)||\rightarrow 0$ for all $f\in C(X)$, $r\in G$.
\end{proof}
%---------------------------------------------------------------------------------------%
The following is an example of a remark.
%---------------------------------------------------------------------------------------%
\begin{remark}
The purpose of this remark is to refer to the Theorem
\ref{theo1}. We also want to \cite{Brown, Connes}.
\end{remark}
%---------------------------------------------------------------------------------------%
Again, note how we refer to Theorem \ref{theo1} and formula \eqref{2.1}.
